My dog has small matted bit of hair. She won’t let me near her with scissors but she doesn’t mind me running through the hair with clippers. It’s on the longest setting at the moment so isn’t actually cutting the hair. I am not sure if it will take the matts off , or will it get tangled and pull at the hair? Does anyone know? I have considered taking her to the groomers and may just have to do that . But I just thought if this worked it may be easier for her. She doesn’t need regular grooming really. Brushing pretty much keeps on top of most matts it’s just these ones which appeared when she was with friends for a few days and wasn’t being brushed regularly during that time
